Spring Boot search is not working properly

All we need is an easy explanation of the problem, so here it is.

Here I want to retrieve Hotels by hotel name, but it is only returning the Hotels which have first letter which I have included.

I have search Hotel name as "Sigiriya", but when I type "s" it’s resulting Sigiriya. But when I start typing more ("igiriya"), the results were gone.

/**
     *
     * @param searchkey
     * @return - List of hotels
     */
    public List<Hotel> searchHotelByName( String searchkey){
        searchkey = searchkey.toLowerCase();
        searchkey = "%" + searchkey + "%";

        return hotelRepository.findAllByHotelNameContentLike( searchkey );
    }

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

I think the reason is even though you are converting the search key to lower case, your database is containing upper case letters. Therefore use ignore case search.

/**
     *
     * @param searchkey
     * @return - List of hotels
     */
    public List<Hotel> searchHotelByName( String searchkey){
        searchkey = searchkey.toLowerCase();

        return hotelRepository.findAllByHotelNameIgnoreCaseContaining( searchkey );
    }

Method 2

Use the contains JPA keyword

public List<Hotel> searchHotelByName( String searchkey){
    return hotelRepository.findAllByHotelName IgnoreCaseContaining( searchkey );
}

contains takes care of % etc.

Note: Use and implement method 1 because this method fully tested our system.
